Do this only after writing all direct and assisted ladder logic for controlling
screw-rotate jogs.

Rotate the ram (screw) by jogging. Experiment with values you entered in
the jog configuration block (JGC) until you obtain the desired jog
operation.

If You Observe This Condition:

Then Make This Adjustment:

Rough jerky acceleration or deceleration

(hammering hydraulics)

1) Decrease jog pressure

2) Decrease jog flow

Sluggish acceleration or deceleration

1) Boost jog pressure

You must download the JGC block to the QDC module each time you
change one or more of its values to implement the new value(s). Use
download bit B21/1. If necessary, refer to the download procedure in
chapter 4.
